Product Description

This Advanced Handheld Underground Cable Fault Locator is a versatile diagnostic tool designed to pinpoint faults in underground cables—including power, control, and communication lines. Incorporating Time-Domain Reflectometry (TDR) alongside Potential and Capacitance Comparison methods, it enables precise detection of faults across a broad voltage range (440V to 400kV) when used with a surge generator.

• Multi-technique approach: TDR for fast, graphical fault analysis; Potential/Capacitance Comparison for physical pinpointing

• Supports both LV and HV cables (with surge generator)

• Handles long cable runs up to 5 kilometers

• High ±5% fault location accuracy

• Ergonomic and handheld design ideal for field operations

• Rechargeable Li-ion battery for portable, long-duration usage

• Includes probe with three claws or rod, and headphones for audible fault feedback

• Integrated LCD or signal display (varies by model)

• Power utility fault maintenance (underground HT/LT cables)

• Telecom and control cable diagnostics

• Industrial plant cabling inspections

• Civil and infrastructure underground wiring checks

• Emergency response for electrical failure localization

The Noyafa Pipe and Cable Locator Kit is designed for efficient underground and in-wall detection of various types of pipes, including PVC, plastic, cement, iron, and metal. The system includes a transmitter that sends a 300 Hz signal over distances up to 40 meters and a receiver capable of detecting this signal through metal (up to 60 cm) and non-metal (up to 15 cm) surfaces. Both devices are powered by long-life rechargeable lithium batteries, ensuring portability and field reliability.

• Transmitter Signal Range: Effective coverage up to 40 meters.

• Receiver Detection Depth: Detects metal pipes up to 60 cm and non-metal up to 15 cm.

• Long Battery Life: Transmitter (10 hrs), Receiver (20 hrs) operation.

• Rechargeable Batteries: Environmentally friendly and cost-effective.

• Adjustable Sensitivity: Allows fine-tuning in varied field conditions.

• Wide Application Scope: Suitable for use with multiple pipe materials including PVC and metal.

• Temperature Range: Operates reliably from 0
